# PSYB01H3 Lecture Notes - Lecture 10: Repeated Measures Design, Statistical Hypothesis Testing, F-Test

## Document Summary

Week 11 lecture #10 monday, july 27, 2015. Contrast the three ways of describing results: comparing group percentages, correlating scores, and comparing group means. Describe a frequency distribution, including the various ways to display a frequency distribution. Describe the measures of central tendency and variability. Describe the use of a regression equation and a multiple correlation to predict behavior. Discuss how a partial correlation addresses the third-variable problem. Order the levels from lowest to highest. Intervals between levels are equal in size. These are relevant to the types of experiments being conducted. Analyzing the results of research investigations what to do with data. Three basic ways of describing the results: comparing group percentages. Example: ask boys and girls whether they like school. Find that 60 boys and 70 girls like school. Perform statistical analysis to determine if difference between groups is significant.
